SLEEPING BAG.

Application filed March 14, 1928. Serial No. 261,480.

This invention'relates to improvements in sleeping-bags for use by hunters, prospectors, miners, motorists, campers, and such other individuals as may be required, or who may I desire, to sleep in the open and be protected from the inclemency of the weather.

The primary object of my invention is the provision of a water-proof sleeping-bag of improved and simple construction, that is compact andreadily arranged for use, that is comfortable and nonheat-radiating, and that affords a. complete protective covering for the sleeper without in any manner affecting perfect ventilation.

A further object of the invention is the provision of a sleeping-bag embodying an inner and an outer envelope, the outer being formed for water-proof material and the inner preferably of a water-proof quilting known to the trade as kapok, or of wool,

eider down, cotton linters, or any suitable soft bedding material, the two envelops being separated at top and bottom to provide top and bottom air-spaces, affording to the sleeper a surrounding element of a nonheatradiatin character and an additional aid to his com ort.

An additional object of the invention is the provision of a sleeping-bag the outer en- 0 velop of which is of water-proof material and bears as an integral part thereof a protective canopy or awning, the envelop and canopy being formed from a single elongated strip of material cut to pattern.

Other objects and advantages of the inven tion will become apparent as this specification progresses and be more fully pointed out in the claims hereto appended.

In the accompanying two sheets of drawings, forming a part of this specification, and

i in which similar characters of reference refer to like parts, throughout;

Figure 1 is a perspective view showing the preferred embodiment of my sleeping-bag as made-up for occupancy.

Figure 2 is a perspective View of a slightly modified form of bag showing a canopy or awning forming a. perfectly ventilated covering for the occupants head; Figure 3 is an enlarged transverse section. taken through the bag, showing the inner and outer envelops arranged to provide an air-space therebetween above and below, the section being indicated by the line 33 in Figure 1;

Figure 4 is a plan view of the bag, showing the bag proper and its awning section, as a whole, flattened out;

Figure 5 is a schematic view showing the shape of the outer covering blank before being sewed together; and

Figure 6 is a diagrammatic view illustratwo of the method of folding the continuous strip of material in forming the outer envelop and its canopy or awning.

Referring to the drawings with greater particularity the bag in a general way, is represented by the numeral 10, and comprises an inner envelop 11 and an outer envelop 12. This outer envelo 12 is preferably formed from an elongated piece of water-proof ma.- terlal and comprises a lower section 13, an upper section 14, and an integral awning section 15, Figure 5.

The inner envelop 11 comprises an upper and a lower piece of quilted material 16 and 17 of the same width and length as that of the sections 13 and 14 of the outer envelop, these pieces 16 and 17 being laid upon the inner surfaces of the sections 13 and 14 and the whole stitched together at side edges 18, upper end 19, and foot end 20.

The material at the lower end-fold of the outer envelope is provided with an infolded section 21, Figure 6, to which and through which lines of stitching are run to secure the pieces 16 and 17 of the inner envelope and the infolded section together, the seams at the side edges and bottom end of the bag being turned in, as shown in Figures 3 and 6. The stitching together of the inner and outer envelopes 11 and 12 in this manner provides air-spaces 22 and 23 there-between, these permitting therewithin a free circulation of air and affording an additional envelope of air serving to prevent the too free radiation of warmth from the occupants body.

One side edge of the bag is left open from a point about midway between the foot end 20 and the upper end 19 to provide an open- 100 ing 24 having fastening means 26 and 27 of any suitable character, such as buttons, snaps, laces or hookless fasteners for securing these edges together, when open the free corner 25 being adaptable for folding-back to permit 105 freedom of entrance to or exit from the bag. The bag may be constructed to open down one side and across the foot end so that it may be used as a blanket or quilt, thus affording extra ventilation on warm nights and also permit- 110 ting it to be completely opened up and aired and sunned as a sanitary measure when not in use.

The awning section 15 may be slightly widened toward its outer end, as shown in Figures 4 and 5, and provided at its inner end with opposed pairs of eyelets 28 and 29 so arranged that, when the section 15 is doubled over in setting up the awning. these eyelets will be disposed in superposed relation, or in registration with each other, and serve as means through which pins, or pegs. 30 may be driven to secure this end of the bag to the ground. as shown in Figures 1 and 4. Midway between the inner and outer-ends of the awning an extra piece of material 31.is laterally disposed and stitched thereto by a double row of stitching,'forming a pocket'for the ridge piece 32 of the awning section, the outer corners of the flap forming the awning being provided with eyelets 33 and 34 for the reception of guy-ropes 35 and 36.

The bag shown in Figure 2 is the exact counterpart of that shown in the various other views, except in that the awning section has been shown, as provided with side flaps 37 havlng gauze or screen covered wmvdows or openings 38, providing ventilation and protection against insect-s.

In making camp for the night, a reasonably level piece of ground is selected, and the bag placed and pnrolled thereupon in flattened out condition, as shown in Figure 4. Suitable pins, or pegs, 30 are next driven through the eyelets 28 and 29 into the groundto hold the head end in secured. position thereon. Small supporting poles 39 and40 are now driven into the ground upon opposite sides of the'bag and the ridge piece 32 carriedby the awning secured to the upper ends of these poles and the awning finally drawn taut by means of the cords 35 and 36. these being attached toipins, or pegs. 41 and 42 driven into the ground upon opposite sides of the bag and about midway between its ends.

My invention resides mainly in the novel method of forming the outer bag, or envelop, and the awning section from a single piece of water-proof fabric, this greatly enhancing its strength and duralnhty, while at the same time producing a more nearly waterproof construction and a bag the various partsof which may be the more readily assembled and secured together. No sleeping-bag, with-' in my knowledge, has ever been produced embodying an inner and an outer envelop united at edges by all around stitching to atford an upper and a lower air-space; nor has there been one produced embodying as a feature in its construction an outer envelop and awning in combination formed from a single,

blank or fabric pattern, as is herein shown and described.

forming both lower and upper sections therer .of and having an infolded section at the foot end thereof to which the foot end of the inner envelop is stitched, the said envelops pro- ,viding intermediate sections forming airspaces extending laterally and longitudinally between the lines of stitching.

3. A sleeping-bag comprising, in combination, an inner envelop and an outer envelop, said outer envelop consisting of a single piece of material forming an extension constituting an awning, a base section, and an upper cover section, an infolded section formed at the folding point of said base and cover sections, the outer edges of both inner and outer, envelops being securely stitched together.

In testimony whereof I have aflixed my signature.

JACOB G. LEIBOLD.
